ThunderWheels version: Demo 0.1
Before editing anything make backups! And be carefull with the new values you use!
*** Sound effects - Vehicles ***
Sound effects in vehicles are configured in the same config file used for the physics, so go to the folder:
- Code: Select all
(your drive:\program files\)ThunderWheels\media\cars
There you'll find some .cfg files, they are named using the following rule: nameofthecar.cfg so if you want to tune up the WildcatMonster car just open and edit: wildcatmonster.cfg, to do that use any text editor... for example Notepad++ (works very well and it's free!).
.cfg files are used in almost everything in ThunderWheels, they are just INI files with the clasic format:
'key = value' pair and the special character '#' to mark lines as comments.
Well, by now you should have that file opened in front of your face and asking yourself what the heck are those parameters and values....
Don worry, i'll explain them now...
See the section [sound] it should looks like this:
- Code: Select all
[sound]
#
# <-- remember, this is a comment
#
engine_sound_file = engine_set_a_2.wav
engine_max_throttle_pitch = 2.0
engine_min_throttle_pitch = 0.25
engine_pitch_multiplier = 3.0
engine_max_throttle_gain = 0.75
engine_min_throttle_gain = 0.5
engine_distance = 40.0
skid_sound_file = skid_0.wav
skid_max_gain = 0.15
skid_multiplier = 0.1
skid_distance = 30.0
Ok, i'll go one by one explaining the posible values and the meaning, as usual lets begin with the first one:
- Code: Select all
engine_sound_file = engine_set_a_2.wav
Meaning: This is the sound file used to make the engine sound. It will be played in continuous loop.
Possible values: any sound file with .wav or .ogg extension or leave it empty if you dont want any sound effect.
The game will look for the file in this folder:
(your drive:\program files\)ThunderWheels\media\sound\effects
Restrictions: the filename cannot contain spaces.
- Code: Select all
engine_max_throttle_pitch = 2.0
engine_min_throttle_pitch = 0.25
Meaning: The pitch is a variation in the frecuency of the sound effect, it is expressed as a factor, so having 1.0 means 100% of the original frecuency (no change) 0.5 means 50% of the original frecuency and so on... The min value will be used when the player isn't pressing the throttle key, and the max value when the user press the throttle key (the player is accelerating the vehicle).
Restrictions: values have to be in the range (0.0, k] where k is a positive real number.
Tip: take in count that more difference between min and max values produces more frecuency range so you get better effect.
- Code: Select all
engine_pitch_multiplier = 3.0
Meaning: The pitch applied to the effect is calculated with the current speed of the vehicle and the maximum speed allowed for that vehicle. The pich will be always in the range of: [engine_min_throttle_pitch, engine_max_throttle_pitch]
*BUT* this parameter lets you modify how fast the 'engine_max_throttle_pitch' value will be applied as the current pitch.
So, for higher values the engine will sound at full load even if the car has a low speed.
Restrictions: values have to be in the range (0.0, k] where k is a positive real number.
- Code: Select all
engine_max_throttle_gain = 0.75
engine_min_throttle_gain = 0.5
Meaning: The gain is also a factor but it controls the amplitud or the volume level of the effect.
The min value will be applied when the engine is in 'ralenti' and the max when the players press the throttle key (accelerates the vehicle).
Restrictions: values have to be in the range [0.0, k] where k is a positive real number.
- Code: Select all
engine_distance = 40.0
Meaning: This is the distance in meters used for distance attenuation calculations. For small values the sound effect will be almost unheard if the listener is far away.
But since ThunderWheels uses surround sound the lower the value, the better the spatial effect for the listener.
Restrictions: values have to be in the range (0.0, k] where k is a positive real number.
- Code: Select all
skid_sound_file = skid_0.wav
(skid is the sound effect used when the vehicle is sliding)
Same as: engine_sound_file, leave it empty if you dont want the effect.
- Code: Select all
skid_max_gain = 0.15
Meaning: The maximum gain applied to the sound effect.
Restrictions: values have to be in the range [0.0, k] where k is a positive real number.
- Code: Select all
skid_multiplier = 0.1
Meaning: The gain applied to the sound effect is calculated with the longitudalImpulse & lateralImpulse average in the wheels of the vehicle, this multiplier lets you modify how fast this sound effect gets heard using the skid_max_gain.
Restrictions: values have to be in the range (0.0, k] where k is a positive real number.
- Code: Select all
skid_distance = 30.0
Same as engine_distance.
Almost every sound file has a different volume level, so if you want to tune up the sound levels (the gain) for a vehicle my advice is to tune up the paremeters in this order:
1- engine_max_throttle_gain, engine_min_throttle_gain and leave an empty value for skid_sound_file (to supress the noise comming from that source).
2- if the 1 isn't enough try changing engine_distance.
*** Background music - Race ***
Background music configured in the main configfile, this file is written from the GUI so you *must* edit the file *before* running the game!
go and edit:
- Code: Select all
(your drive:\program files\)ThunderWheels\config\thunderwheels.cfg
The things you can edit in this file are:
- Code: Select all
sound_collisioncarcar = BATHIT1.WAV
sound_collisioncarcar_distance = 10.0
sound_collisioncarcar_gain = 0.75
sound_tracks = Born_To_Be_Wild_mono.ogg WhoMadeWho.ogg Thunderstruck2.ogg
sound_tracks_distance = 100.0
sound_tracks_gain = 1.0
tracks = la_falda pecos tanti
Having read the sound effects documentation (see above) you have enough information to edit and modify any sound_collisioncarcar_XXXXXX value
If not, go and read this post from the beginning.
Ok, i'll try to explain it briefly.... see this:
- Code: Select all
sound_tracks = Born_To_Be_Wild_mono.ogg WhoMadeWho.ogg Thunderstruck2.ogg
tracks = la_falda pecos tanti
The value for 'tracks' is a list of track names, for Demo 0.1 there are only those three tracks to run. Each track name cannot contain spaces (same for soundfiles) and each name must be separated with a space.
They will be loaded in the same order as they are listed.
The value for 'sound_tracks' has the same logic as 'tracks', the restriction here is that the sound files used as background music HAS TO BE IN OGG FORMAT! it cannot be a .WAV.
If you run three tracks you have to put three sound files, if you dont want music for one or all tracks just write None. For example:
- Code: Select all
sound_tracks = Born_To_Be_Wild_mono.ogg None Thunderstruck2.ogg
tracks = la_falda pecos tanti
The above configuration will make run the tracks (by tracks i mean circuits):
la_falda with Born_To_Be_Wild_mono.ogg
pecos with no music
tanti with Thunderstruck2.ogg
The last thing to say:
- Code: Select all
sound_tracks_gain = 1.0
Will set the gain for *all* the music files loaded in the tracks
Well, if you're still reading this, you deserve a reward! specially for the effort required to understand my english
.... Feel free to post and ask questions.
